Fuente: Wipo "Sensorization" A robot, includes: a driver; a plurality of sensors; a memory; and at least one processor configured to transmit a first signal for identifying a presence or absence of an object within a sensing area of the plurality of sensors through a first sensor operating in the signal transmitting mode from among the plurality of sensors during a first time period, identify, a second sensor to transmit a second signal during a third time period after elapse of the second time period from among the plurality of sensors, transmit the second signal by operating the identified second sensor in the signal transmitting mode, identify a location of the object based on whether a second reflection signal corresponding to the second signal is received at the second sensor, and control the driver to travel by avoiding the object based on the identified location of the object.
